Tunnel Cleaning Vehicle with High Pressure Washing System

The tunnel cleaning machine sprays detergent solutions via high pressure on tunnel walls, subway walls and landmarks, and then brushes dirt away.

The cleaning brush for the tunnel washing unit is installed with a two-section articulating boom jack with a 270 degree revolving angle to both left/right and up/down directions so it can brush the interior tunnel wall and be sprayed and flushed clean by a high pressure water pump. A large water tank allows users to clean more at one time and the cleaning brush is removable if needed.
